Spraying vinegar on garden?

Spender£

I have an area of garden where anything that i plant gets stripped of all it's leaves and killed, I have tried fruit trees, pyracantha, berberis and all have been defeated by whatever is doing this apart from the native blackberry brambles which keep coming up although even they have struggled a bit being partly stripped.

I don't really want to pay for those expensive chemical sprays so i read an article online claiming you can use dish soap, baking soda or vinegar or a mixture.

Anybody tried anything like this and would it help or be worse with the acidic nature of vinegar.

Will only brown the leaves.

Sprayed on white vinegar works well on the dandelions on my patio, but I think you need to identify what the plant noshing culprit is...

I think you might need an automatic wildlife camera. But why do you want to throw the kitchen equivalent of Agent Orange at the problem; surely that will just make things worse?.

Something that eats pyrocanthya must be an alien.
Are the leaves nibbled? 
Any colour or spots?
White cobwebby stuff?
